To all whom it may concern.-

Be it known that I, GEORGE J. RECORD, a citizen of the UnitedStates,residing at (Jon- .neaut, in the county of Ashtabula and State ofOhio, have invented certain new and useful Improvements in Caps forCans; and I do hereby declare the following to be afull, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention is in part an improvement on Letters Patent No. 47 6,309,granted to me June 17, 1892. Said Letters Patent related moreparticularly to the sealing of nozzles of cans for oil or other liquidthough not exclusively restricted thereto.

The chief object of the present invention is to provide satisfactorysimilar means for sealing the inlet through which the liquid is suppliedto the interior of vthe can, this inlet being preferably a screw neckhaving removable screW-cap, and the latter being provided with a smallnozzle and air-inlet apertures in order that it may be used also forpouring out the liquid as desired. To this end I employ the constructionand combination ofdevices hereinafter more particularly set forth andclaimed.

In the accompanying drawings, Figure 1 represents a perspective view,taken from the inner side, (if a screw-cap constructed accord- Fig. 2represents a similar view of the seal used therewith in one form of thesaid invention. Fig. 3 represents a similar view of the tubularscrew-cap. Fig.

' irepresents a central vertical section through the devices shown inthe three foregoing figures when put together for use in sealing theinlet. Fig. 5 represents a detail perspective view of another form ofthe screw,having its top closed integrally so as to need no other seal;and Fig. 6 represents a detail perspective view of a thin sealing diskwhich is sometimes substituted for the seal before described and usedwith the open screw and the screw- Adesignates the screw neck throughwhich the receptacle is filled with liquid. B designates the screw capwhich turns on and off this screw and is provided with a nozzle B alsowith air inlets b b, respectively in the top of the nozzle and in thetop of the cap below it. A larger opening b permits the liquid to flowout of the can through the said cap to and through the said nozzle. 0designates a seal of thin metal, approximately shaped like a plate,provided'with a flange'c, which rests on a lower inturned flange b ofthe upper part of the said screw and having on its periphery small beadsor lugs c, which snap under the said flange b The operation is the sameas inthe patent aforesaid and is attended by similar advantages. Afterthe can or other receptacle has been filled through the said tubularscrew, the seal is snapped in place and the screwcap is turned home. Atany subsequent time the screw-cap may be unscrewed, the seal cut away,the screw-cap replaced, and the liquid poured out through the nozzle B.Of course the seal may also be used with a cap having no nozzle.Sometimes, as shown in Fig. 5, I dispense with a separate seal, andcover the top of the screw neck A with a plate A, the twobeing'integral. This plate is itself a very eflfective seal, and, beingthin,

may easily be ,cut away. The screw cap B is applied, removed, and usedas before. Also, I sometimes substitute a thin sealing disk D (Fig. 6)for the seal before described securing it to the inner face of thescrew-cap by adhesive material or in any other convenient way, so as toclose the 'air vent and liquid outlet. So long as the screw-cap is inplace and this disk or lining is intact the tubular screw is sealed. Byremoving the screw-cap, cutting away the disk or lining and replacingthe screw-cap the receptacle is made ready to pour out its contentsthrough the spout A. When the seal 0 is used, it is preferablysurrounded by a rubber gasket E for greater tightness; but this is notindispensable.

This invention is very serviceable for petroleum cans, harness oil cansand in fact all receptacles of fluids that are to be sealed and storedor transported; especially if they are to be used for supplying lessquantities'through the same aperture which is served for filling them.Of course the tubular inlet and its cap need not be screw-threaded; anyordinary means of attachment allowing removal being used instead.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A receptacle having a filling opening and a screw-neck for saidopening provided with an internal flange, in combination with asealingdisk 01' seal of thin material having projecting parts which snap underthe said flange and hold the sealing disk or seal against withdrawalsubstantially as set forth.

2. A receptacle having an opening surrounded by an inwardly extendingflange, in combination with a sealing disk or seal of thin materialhaving projecting parts which snap under the said flange and hold theseal-
